It appears to be some sort of CO2 based charged air kit and looks cool to me and actually might work...It would not cause the potential engine damage like nitrous can,although I am sure would not make that kind of power either.I like the philosophy behind it,plus it won the annual SEMA show's top award!..Somebody got some info about this,or did I stumble upon something for debate here?

It's like nitrous but you won't get the same amount of hp. But that sometimes a good thing, like when it comes to cares that don't have parts availible to make it strong.
I'll let you know how it works when I install it on my buddies car.

you use that on a air to air i/c to cool the i/c making it more eficcent

Yeah it sounds as though It would do wonders to assist an intercooler further,but it also says it can be used on a normally aspirated engine..Like nitrous but maybe with less worry?...

no, N2O is a extreme oxidizer, and when it's on, it floods into the engine in place of regular air or with air and it's almost as if you've got pure oxygen in your cylinders. This thing doesn't spray CO2 into the engine, that'd ruin performance completely. It cools the air coming into the engine significantly (by their claims anyways) and because cold air is more dense you're getting more oxygen into the engine to help with combustion. It seems more like a glorified cold air intake really. The intercooler thingie looks very useful though. I could see the benefits of this thing on a turbocharged engine, but not on a naturally aspirated engine.

subzero

should do great things on an intercooled car,but like you said zerotosixtyv8;The gains on a normally aspirated car would be minimal probably...I really want to see some performance data on this though as maybe it will suprise some of us...

#1 rule being ignored in most "cold air" setups. When you change the temperature of a fluid in a closed system (which is how the air can be modeled after it enters the induciton) you change the PRESSURE not the DENSITY. These are two very different things. If I heat up an aerosol can did I change the density of the stuff inside? Well, not until it explodes right? Did I change the pressure?
You only get more power when the atmospheric air is colder. It looks to me like it is injecting CO2 into the intake. Because it is so cold it reduces the air temperature. The only way this might help is that it could possibly cause the cylinder to fill better, but colder air doesn't move nearly as well as warm air. The other thing it could help is detonation. Auto ignition is a function of intake air temperature which is why boosted cars are intercooled. So on a boosted application this could work well because you could run more boost without worrying about detonation. On an NA engine you could run higher compression on cheap gas for several reason. 1. the auto ignition temperature is lowered 2. There is more inert gas in the system which will slow the burn down. It could also work well on a Nitrous system for the same reason. I say file this brilliant invention right next to the amazing fuel tornado thing and the electric super/turbo charger.

alot of the air that flows over the IC can end up even in a very mixed way in the engine compartment. I would rather have trace amounts of nitrous floating around my engine comparment than trace amounts of CO2. There wouldnt be enough N2O to do any damage but it could do some good, the CO2 on the other hand could only work to dampen combustion if it is floating around where the filter could pick it up.

Well, I can't seem to open their page, but if I'm following they're blowing a compressed gas over an intercooler to cool things farther then they could with air.

ATOMonkey, yes, that's true for a closed system, but an engine isn't a closed system. An extreme example of this is a turbo setup where the boost pressure is regulated by a wastegate. When the intake charge is cooled the turbo just keeps pumping more air till boost pressure is maintained, so essentially you get more dense air at the same pressure, which means more power.

This is what Im talking about, the original cryo intercooler chiller http://www.nitrousexpress.com/produc...oc=101&dealer=

so,does anybody like it enough to try it?....guinea pigs anyone?

It doesn't spray C02 into the intake. It has a bulb type system that cools the air in the intake. Think of it has a refrigerator. For the intercooled cars, it uses a line to send liquid C02, same as the bulb, but it cools the air before it passes through the intercooler.

Don't believe me, take time to read before you answer...

I guess you are missing my point, on most cars anything that is sprayed in the underhood area is likely to find its way into the air that is going into the engine, since this is the case. Any which way you look at it (even on cars that have cold air kits sometimes), I would rather have the under hood air on my car "contaminated" with trace amounts of nitrous instead of CO2. Im sure with a valve change to his system you could replace the CO2 bottle valve with a N2O valve to allow use of nitrous in his system, but how much cheaper than the NX one is it?

it looks to me it dose bolth:lala:

I agree, I was just trying to get the point across that the engine will not run if it was sprayed directly into the plenum or intake tract. This just cools the metal, in turn, cools the air. Where would you charge the bottle up and how long will it last is my question.

They claim that it will cool the intake air 35%, and the intercooler systems 50%. Don't know about anybody else, but that is very, very hard to believe.
